The correct response is: It is the proportion predicted to be present in the early universe.
The proportion of hydrogen and helium in the universe supports the Big Bang theory because it matches the predictions made by the theory. According to the Big Bang theory, the universe began as an extremely hot and dense state before expanding and cooling down. As it cooled, protons and neutrons were able to combine to form helium nuclei. The abundance of hydrogen and helium observed in the universe today is consistent with the predictions of the Big Bang theory, providing strong evidence for its validity.
The correct answer is:
1. It is the proportion predicted to be present in the early universe.
Explanation:
The proportion of hydrogen and helium in the universe supports the Big Bang theory because it matches the predicted proportions from the early universe. According to the Big Bang theory, the universe underwent a rapid expansion and cooling after the initial explosion. During this expansion, hydrogen and helium were the first elements to be formed in large quantities. The high temperatures and energy of the early universe allowed for the fusion of hydrogen nuclei into helium nuclei, resulting in the observed abundances of these elements today. Thus, the actual proportion of hydrogen and helium in the universe aligns with the predictions made by the Big Bang theory, providing evidence for its validity.
